     [ https://issues.apache.org/jira/browse/FLINK-15506?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andrey Zagrebin closed FLINK-15506.
-----------------------------------
    Release Note: 'state.backend.rocksdb.ttl.compaction.filter.enabled' is now true by default. Disable it only if you experience serious performance degradations during RocksDB compaction.
      Resolution: Fixed

The common performance benchmark looked good.
